package/binutils: xtensa: fix shrink_dynamic_reloc_sections
This fixes the following build error caused by link-time relaxation removing copies of literals that reference undefined weak symbols with PLT entries created due to -rdynamic option passed to g++ link command: ld: BFD (GNU Binutils) 2.31.1 internal error, aborting at elf32-xtensa.c:3292 in elf_xtensa_finish_dynamic_sections Fixes: http://autobuild.buildroot.net/results/d41/d41aae8a448c316187f9fbde40f1d077182bb244/ Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

+Subject: [PATCH] bfd: xtensa: fix shrink_dynamic_reloc_sections for
+ export-dynamic
+
+shrink_dynamic_reloc_sections must remove PLT entry that was created for
+an undefined weak symbol in the presence of --export-dynamic option when
+relaxation coalesces literals pointing to that symbol. This fixes the
+following assertion:
+
+ ld: BFD (GNU Binutils) 2.31.1 internal error, aborting at
